If you figure out a less expensive alternative, let us know. An alternative that includes new internals, seals, and bearings and labor.

Luckily, I saved on labor - I had a friend with me - he knew modern rear ends. We figured out the old torque-tube and it runs like a charm (check the Stovebolt Tech Tip by Sweet). I bought the tools I needed (run-out gauge and magnetic base holder?) from Harbor Freight. Prussian Blue "grease" is readily available (Permatex).
